First off: NC is fairly insensitive to ignition. If we can ball mill black powder dry, why not NC? The problem is that NC is also very strong and flexible, quite undesirable properties for grinding. So ball milling with lead is probably going to be slow, and with heavy contamination. Brass or copper media (also safe for BP) might work better.

Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.
A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.
